A congenital nevus is a proliferation of benign melanocytes that is either present at birth or develops shortly afterwards. Congenital nevi are usually classified by size: small (less than 1.5 cm in diameter), medium (larger than 1.5 cm and up to 20 cm) or giant (measuring 20 cm in diameter or larger).
Scoliosis is a common condition related to syringomyelia in children; in fact, some studies have shown that more than 50% of children with a syrinx have abnormal spinal curvature.coliosis can be caused by congenital conditions, neurological conditions (like SM), or can be of unknown origins. 80% of scoliosis cases have an unknown cause and are labeled idiopathic. Treatment options include observation, bracing, and surgery.
Two American studies quote the incidence of scoliosis in syringomyelia to be about 60% If a child develops symptoms of scoliosis before age 16 the eventual incidence of scoliosis is 82%, if later than age 16 symptoms develop, the incidence is 48%.wo American studies quote the incidence of scoliosis in syringomyelia to be about 60% If a child develops symptoms of scoliosis before age 16 the eventual incidence of scoliosis is 82%, if later than age 16 symptoms develop, the incidence is 48%.
